dawn: source bundle trimming #758
Description
Most users don't have to download a Dawn source tarball. Still, we should try to trim it down further.
Downloading a source tarball for Dawn + all its dependencies is 91MB, right now. Noting some things for myself to follow up on to reduce that.
The uncompressed archive is 856M:
du -sh ../dawn-9e2a193db129ebaf42eccfb9d6bb40055645c5d9 | gsort -h
856M ../dawn-9e2a193db129ebaf42eccfb9d6bb40055645c5d9
We should be able to reduce that to ~124M if we do the following:
% du -sh ./* | gsort -h
...
1.2M ./tools
10M ./out
28M ./src
159M ./test
655M ./third_party
test can likely be removed:

159M ./test/tint

We could also remove swiftshader (software vulkan implementation), we don't use anything from it afaik (same for angle the opengl es software impl?):
% du -sh ./third_party/* | gsort -h
4.0K ./third_party/go.mod
364K ./third_party/ninja
1.6M ./third_party/vulkan_memory_allocator
1.9M ./third_party/zlib
2.7M ./third_party/khronos
7.4M ./third_party/gn
12M ./third_party/abseil-cpp
52M ./third_party/angle
67M ./third_party/vulkan-deps
510M ./third_party/swiftshader
We should be able to remove gn, or at least webgpu-cts:
du -sh ./third_party/gn/* | gsort -h
8.0K ./third_party/gn/abseil-cpp
8.0K ./third_party/gn/glfw
7.4M ./third_party/gn/webgpu-cts
Lastly, we can remove vulkan-headers as it is duplicative of https://github.com/hexops/vulkan-headers
